SDR# on a Toshiba Encore tablet PC

SDRSharp-ToshibaEncore-LondonShortwaveSWLing Post reader London Shortwave recently moved the Software Defined Radio (SDR) application SDR# (“SDR Sharp”) off of his MacBook Pro and onto a Toshiba Encore 8″ tablet PC. He recently posted this video of SDR# running his FunCube Dongle Pro+ on the Toshiba Encore tablet:

His reception of the Voice of Korea’s Spanish service is most impressive, especially considering the high level of RFI (radio noise) he must cope with at his home in London, England.

SDR# now has AM synchronous detection

LondonShortwave-Park

SWLing Post reader, London Shortwave writes with a remarkable story about the free SDR application, SDR#(or, “SDR sharp”). He writes:

“Two days ago, I emailed Youssef (SDR# developer lead) to ask if he would consider adding synchronous AM detection to his software at some point.

To my great surprise he e-mailed me back the same day and told me that it wouldn’t take him long to write the necessary code. A few hours later he sent me a preview copy of the software with the feature included (all I had to do was to swap one .dll file in the version I had installed at the time). The following day, he integrated it into the latest release!

With the new sync detector the software is rapidly becoming my favourite SDR application.

Here’s a demo video I made for Youssef (and everyone else!) to show how I’ve been getting on with it:

This is amazing–what’s especially impressive is that a first iteration of AM sync should be so well implemented.  I love the way you can use the IF shift to block out interference within a sideband, much like USB/LSB selectable sideband. There are paid and OEM SDR applications that can’t do this.

London Shortwave: you’ve convinced me to see if SDR# will drive any of my receivers. Many thanks!

Testing SDR#’s noise reduction in a London park

LondonShortwave-ParkSDR

Yesterday, SWLing Post reader London Shortwave took his laptop, FunCube Dongle Pro+, and 6 meter long wire antenna to a local park where he tested SDR#‘s new IF noise reduction.

He made the following screencast/video where he toggles the IF noise reduction feature while receiving the BBC World Service’s Pashto language service on shortwave:

Most impressive! Indeed, I believe SDR#’s noise reduction might rival that of OEM applications. While I’m not the biggest fan of noise reduction for everyday use (due to inherent digital artifacts) it is a valuable tool when noise levels are high.
